Washington -LRB- CNN -RRB- -- The Federal Aviation Administration Wednesday proposed a $ 2.9 million fine against American Eagle Airlines for allegedly conducting more than 1,100 flights using planes with landing-gear doors that had not been repaired as prescribed by the FAA .

The proposed fine comes just weeks after the FAA proposed a $ 2.5 million fine against the airline for allegedly operating flights without adequately ensuring that the weight of baggage was properly calculated .

The Fort Worth , Texas-based American Eagle -- a regional affiliate of American Airlines -- flew four Bombardier regional jets on more than 1,100 flights between February and May 2008 , with main landing-gear doors that had not been repaired as ordered by the FAA in August 2006 , the FAA said .

`` Following Airworthiness Directives -LSB- repair orders -RSB- is not optional , '' FAA Administrator Randy Babbitt said in a statement . `` The FAA does not hesitate to levy fines if maintenance standards are violated . ''

American Eagle responded that it was disappointed in the FAA 's actions , saying the airline did not endanger the public and it considered a fine unwarranted .

The repair order required airlines to inspect landing-gear doors and take necessary action , fixing the doors or replacing them with new ones . In this case , American Eagle found damage on four aircraft , but rather than removing the doors as required , the airline repaired them while they remained on the planes .

American Eagle said it self-disclosed to the FAA that repairs were performed while the landing-gear doors remained on the aircraft , a process that the FAA and the aircraft manufacturer subsequently approved , the company said . American Eagle subsequently removed the landing-gear doors on each of the affected aircraft and repaired them in accordance with the Airworthiness Directive .

The airline said it will meet with the FAA to discuss the matter .

The proposed fines are the latest in a string of multimillion dollar fines the FAA has proposed against airlines for failing to follow repair orders . In October , the FAA proposed to fine US Airways $ 5.4 million and United $ 3.8 million for other maintenance violations .

In March , Southwest Airlines agreed to pay $ 7.5 million to settle a complaint that it flew unsafe planes .
